change culture for all pages (in button commant event)

I've used 3 languages on my site and I’ve also put 3 Image Buttons.
The language image button that you click will allow that language to be seen on the site. What should I write for that command btn (btn1_command event)

but when I cllick language button, culture should change for all pages for only current user.

Create base page drived from System.Web.UI.Page named as BaseBage. and InitializeCulture i am setting in base page and all pages I am driving from BasePage instead of System.Web.UI.Page, so there is no need to write this method for each page.

Hope you understood what I mean.

Please let me know if you need more help.
